Hi catmic,
Thank you for your support!
I now patched the UnityPlayer.dll to remove the problem with the InitializeCriticalSectionEx reference. Then I got a new error:
"GLContext: failed to create context: Die angegebene Prozedur wurde nicht gefunden.
Failed to initialize graphics.
Your Windows version seems to be Windows XP, and this
application likely does not support it (it would have to
support OpenGL rendering to work on XP).
InitializeEngineGraphics failed"
I found this article:

So as my graphics driver was from 2008, I updated it and the game started fine.
However there are still issues, in the Intro, after Bernard ate his sausage,
screen goes black and the rest of the Intro is not visible anymore, also when
trying to play the tutorial, I only see a cursor on black background.
I have a GeForce 9400 GT graphics board. Altough it should be DX10 compatible, I experience these weird issues.
I guess you don't have any ideas regarding these problems, do you?
If compilation settings aren't set as mentioned in the article above, would it help to make a special build with these settings?
